Abstract
The invention relates to a process of forming an embossed coated substrate. The process comprises the steps of: (I) forming on a substrate at least one coating whose composition comprises a radiation-curable polyurethane dispersion, (II) embossing the coated substrate on a relief surface, (III) irradiating the embossed coated substrate to cure the polyurethane-containing coating. An application of the process is the manufacturing of caul paper.
Description
The present invention relates to form the method for embossing coating material.
Embossing can be defined as making the surface form burr with the variety of way that comprises pressure mode such as punching press, mold pressing or roll-in.
Can be with the base material embossing of band coating, so as on coating transfer printing texture or other burr.If need, can peel off the embossing coating from base material in addition.So therefore, provide coating or the film that has burr on the one hand, providing on the other hand to remain untouched keeps and reusable base material.
The paper of sheet material or paper tinsel form or shaped plastics base material usually are referred to as generic term " paper ".Tympan paper (caul paper) is the technical term that comprises a few class cruddy papers and curtain coating paper tinsel.These " paper " are used for function surface structure or texture are transferred on another base material.Representative instance comprises artificial leather (polyurethane or polyvinyl chloride-type), furniture paper tinsel, footwear, indoor decoration, handbag, suitcase and suitcase.
According to performance level, have three class embossing " paper ".
1, the common coating that obtains by siloxanes or aliphatic acid chromium complex of anti-adhesion performance wherein,
2, extruded film/ply of paper casting die: these films be thermoplastic and in heating embossing roll gap easy deformation,
3, ULTRACAST technology: 100% acrylate shines with electron beam on the embossing rotary drum and solidifies.
The curing of polymer composition can be by heat (being referred to as " heat cure ") or by other radiation mode, and electron beam irradiation or ultraviolet ray irradiation (being referred to as " radiation curing ") are carried out usually.Radiation curing is more and more preferred, because it needs less energy and throughput rate height than heat cure.The ULTRACAST technology is used radiation curing mode, especially electron beam irradiation.
By the several patents that Scott Paper Company proposes ULTRACAST technology: EP 0 036 883, US4,289,821, US4,322,450, US4,327,121, US4,427,732, US4,840,757 have been described.
The ULTRACAST technology is that high-performance designs, and is to be the most universal in the embossing industry.
Yet this technology is high running cost owing to electronic beam curing has, and in addition, it has narrow range of application.This can draw from the liquid level embossing simultaneously of the mixture of acrylic ester monomer and oligomer and the fact of curing, and this situation has only when the back side by paper and solidifies, and is just possible when avoiding being adhered to knurling rolls.Therefore, can only use high-energy radiation solidification (electron beam).Because liquid property before solidifying and the non-thermal plasticity characteristic after solidifying, the embossing of coating and curing must be carried out simultaneously.The result is difficult and spends big production method.
Described the alternative method of ULTRACAST technology in EP 0 210620A and DE4 421 559A: at first precuring is coated with lacquer, and embossing is then solidified later on fully.This production method also is difficult and spends big.
Therefore wish to find the method easily and flexibly that forms the embossing coating material.Preferably, this method should have economic and practical.
The invention provides the method that forms the embossing coating material, this method may further comprise the steps:
(I) on base material, form at least one coating that its composition comprises the radiation-curable polyurethane dispersion,
(II) embossing coating material on the burr surface,
(III) this embossing coating material of radiation contains the coating of polyurethane with curing.
We it has surprisingly been found that if use the radiation-curable polyurethane dispersion to form coating on base material, can satisfy the purpose of easiness and flexibility so.
The radiation-curable polyurethane dispersion is generally with the isocyanate-terminated polyurethane prepolymer of anion initial preparation, it and hydroxylating acrylate reactions.With the nertralizer of tertiary amine the prepolymer that reacts is distributed in the water then as carboxylic acid functional.Dispersions obtainedly before solidifying, be not clamminess substantially.
This feature makes and embossing and curing operation can be separated on when and where.Can obtain flexible, general production method like this.
For example, this is very significant for producing tympan paper: the surface of coating can embossing before solidifying, and can not be adhered to the burr surface of embossing utensil (usually being knurling rolls).Curing schedule can carry out in off-line, because the uncured coating inadhesion on the curtain coating paper tinsel is in the back side of paper tinsel if suitably.Optionally, uncured paper even can twine, and at another time or another place radiation curing.
In addition, radiation-curable polyurethane can be mixed with the gloss number of wide region.So, it doesn't matter for the final gloss of coating and embossed surface.In fact, this means, use same embossed surface, can obtain different glossiness.
Because gloss, thickness and embossed surface can be arranged by enough same coating apparatus, the present invention has obtained highly freedom in technology and design.
Preferably, dry coating in step (I) and (II).Like this, dry coating before embossing.This drying helps uncured coating to be had desirable low surface viscosity and greatly reduces the risk that is adhered to embossed surface.
Preferably, baking temperature is 60-120 ℃ and/or drying time to be 30 second-5 minute.Find that this temperature/time range can obtain the process speed requirement, do not have or low coating viscosity, and favourable the taking into account between the low-risk of uncured coating aging.
The embossing coating material can be undertaken by different utensils such as mold pressing or pressing plate equipment.Yet, preferably by contacting the embossing coating material with the burr surface of roller.This is the practicality and the low mode of cost of embossing coating, and fully is adapted to large-scale production.
Preferably, embossing step is carried out with the one or more of following feature:
The embossing temperature is 60-220 ℃,
The embossing time is 1-20 second,
Use 5-30kg/cm
2Pressure embossing coating material.
These features are found fast and the effectively embossing that is suitable for providing coating.
Preferably, on base material, apply different two coatings forming.This helps the versatility of this method and can make the performance of whole coating be suitable for required application.
For example, coating must have thermoplasticity, so that can suitably embossing in the embossing step.On the other hand, if coating is transferred on another base material, as preferred, this coating must be enough hard, so that guarantee accurately to peel off and be transferred on another base material, the burr of coating does not fluff diffusing.
Preferably, the hardness of the last coating of these at least two coatings is greater than the hardness of following coating.Following coating should be enough soft, in case accurately embossing, should be enough hard and go up coating, peel off exactly and transfer on the fabric so that guarantee coating.
Preferably, the last coating of these at least two coatings has the silicone additives of containing, the composition of preferred acrylate silicone additives.This additive can obtain well peeling off and transfer printing of coating.
The radiation that is used for solidified coating can be the electron beam irradiation.Yet the irradiation of preferred coatings is carried out with the ultraviolet ray irradiation.The latter is easier to be lower with cost than the electron beam irradiation.
Preferably, in the subsequent step of this method, peel off the embossing coating from base material.More preferably, peel off the embossing coating, be transferred to again on another base material from base material.This can obtain various products such as fashionable leather wear, vamp, handbag and other furnishings.
The present invention also extends to the embossing coating material that comprises the base material with embossing coating that its composition comprises the radiation-curable polyurethane dispersion.
This embossing coating material is significant intermediate products.It comprises can be in the embossing coating of another when and where radiation curing.This is because its composition comprises due to the chemical property of coating of radiation-curable polyurethane dispersion.This dispersion was not clamminess before solidifying substantially, therefore was convenient to storage, the processing of these intermediate products.This intermediate products even can be transported to another factory carry out the final curing of coating.

4, peel off
Perhaps, this tympan paper performance is most important performance; Affinity and bonding force to the embossing coating should be low as far as possible.Tympan paper needs enough " firmly ", to guarantee applying coating quick and suitable peeling off in image transfer method.
Because in fact transfer printing is carried out afterwards immediately at applying coating " water dodges and does ", so temperature can be up to 150 ℃.The heat-resisting quantity (softening) that discovery has only the hard and fine and close crosslinked PUD of UV (#3) to have sufficient to guarantee correctly to peel off under 150 ℃.The relevant stripping performance of the PUD that UV is crosslinked provides in table 4, has reflected the easy degree of the dry coating of can tearing from the paper.

5, solvent resistance
For fear of in the print-on coating method in the attack that tympan paper in the process is subjected to solvent that applies of finishing coat, therefore solvent resistance is most important.The life cycle of paper largely is subjected to the influence of its solvent resistance.
All UV-PUD that discovery is described in presents can tolerate toluene, isopropyl alcohol and dimethyl formamide.They are the strongest solvents of aggressivity that use in print-on coating.Table 6 has shown and is using the solvent resistance result of typical solvent type polyurethane (available from Ucecoat FN 301 and the Ucecoat TCM of UCB Chemicals) carry out the print-on coating in 5 cycles on same tympan paper sample after.UV-PUD is without any any destruction that has shown the patterned structure of paper; Gloss and thin portion structure are not affected.Yet it is softening a little that the tympan paper with the highest UV crosslink density has shown by solvent.
